Version 1.35.3

Added

• Added support for Python 3.
• Added support for standard TypeDef attributes.
• Added support for values of type 'stringarray'.
• Added method Element::setName.
• Extended Python bindings for Document, NodeGraph, MaterialAssign, and Collection.

Changed

• Modified NodeGraph::topologicalSort to return elements in a more intuitive top-down order, with upstream elements preceding downstream elements.

• Updated OSL reference implementations.

Fixed
